God Eater Burst

Like I said, most people play on the US version. For your 2nd question, make sure you put the DLC folder (ULUS10563) at the right place, which is memstick\PSP\GAME. As for your last question, just rename the JP DLC folder into the US/EU DLC folder but this is kinda dangerous as it can corrupt your save file (I dont know how but it may happen). So, back up your save file

Thank you very much!! If i'll use the JP DLC will i have the entire game in japanese?

EDIT: I don't know why but my dlc don't work, ive put the directory ULUS10563 in memstick/PSP/game but when i load the game it said that the dlc can't be loaded, do you know why?

Nah, only JP stuff (weapons, materials etc.) will be in japanese

Make sure it look like this:
